Hey gearheads, At the risk of sounding like a complete moron, I’m faced with a predicament I didn’t really expect would happen. A while ago, my best friend did me a solid and loaned me some cash to buy a ‘68 Charger, which is my dream car. To be clear - he didn’t lend me all of the money, just added less than a third of it so I’d have enough to get my hands on the car. I’ve since paid him back and I thought that would be the end of it. But, no. We live across the street from each other, and the car is in my garage, where I fiddle around with it in my spare time. Every time he sees me working on it, he immediately drops whatever he’s doing and joins me. At first I didn’t mind him and enjoyed the company, but there are times when I prefer to be alone. To make matters worse, he spent his childhood in Australia and doesn’t even like cars. He owns an online business and has done well for himself, especially since it’s a gambling site or something (https://www.wild-card-city.com/wild-card-city-in-australia/). Anyway, the problem is that he doesn’t shut up at all and there are times when he’s just distracting me from working on the car. It’s gotten to the point where he just invites himself over and stays even after I finish working, and the worst part is that he can’t take a hint. I’ve tried explaining things to him, but it’s like doesn’t even hear what I’m saying. I get that I need to let him down easy, but I don’t want to seem ungrateful, especially since he was there when I needed a favor. On the other hand, it doesn’t seem fair that I should repay the kindness for as long as I’m alive, that’s just overkill. Any advice???
